MOUNTING FOR ANTIFRICTION BEARING Filed Jan. 26, 1948 I'MEIIIIIIIIE 3nnemor 3 Basil]? Sroizy attorneys Patented May 10, 1949 UNITED STATES PATENT OFFICE MOUNTING FOR ANIIFRICTION BEARINGS Basil P. Strong, Atwater, Ohio Application January 26, 1948, Serial No. 4,405 g 6 Claims. (01. 308-184) The invention relates to anti-friction bearings, and more particularly to a cushioned mounting or support for ball bearings.
An object of the invention is to provide such a device in which no stress is set up in any member or part of the bearing, due to misalignment or mismounting of the bearing upon the shaft, within reasonable variation.
Another object is to provide such a bearing than a thick flexible material, and which is also less expensive.
Another object is to provide such a device in which the housing contains the bearing within fixed limits.
Still another object is to provide a bearing mounting of the character referred to having end rings which not only form a grease chamber but also hold the two parts of the housing in their respective positions and float with the shaft when flexing of the frame occurs.
The above objects, together with others which will be apparent from the drawing and following description, or which may be later referred to, may be attained by constructing the improved mounting for anti-friction bearings in the manner hereinafter desscribed in detail and illustrated in the accompanying drawing, in which:
adapted to run as in usual practice, the balls being;I preferably retained within a conventional cage 5.
The inner ring 10 of the bearing is fixed upon the shaft IS in any usual and well known manner, preferably having a drive flt upon the reduced portion ll of the shaft, the adjacent side of the ring bearing against the shoulder it of the shaft.
The improved mounting for the bearing in-- cludes a housing formed of two similansemi-circular housing members is each of which has a semi-circular groove or channel formed in its inner side, said grooves being substantially flat I in cross section as shown in Fig. 2.
In order to cushion the bearing within the housing a flat, relatively thin strip of rubber, or. other flexible material, indicated generally at 2|,
with an opening extending through from the 1 exterior flat portion 23 to the central annular channel or groove '20 and a grease fitting 28, of
any usual and well known type, is mounted therein for supplying" grease to the interior of the Figure 1 is a sideelevation of a cushioned ball bearing mounting embodying the invention;
Fig. 2 a-longitudinal sectional view through the same;
Fig. 3 a detached plan view of one end of the gasket located between abutting surfaces of the housing members; and
Fig. 4 a longitudinal edge elevation of one of the flexible strips which form a cushion for the bearing.
Although the invention is applicable to 'the mounting of various types of anti-friction bearings, for the purpose of illustrationv a ball bearing of conventional design is shown comprising the inner bearing ring l0 and the outer bearing ring H having the opposed annular grooves or ball races l2 and 13 in which the balls ii, are
housing. For this purpose an aperture or notch 21 is formed in the adjacent edge portion 01' the flexible cushion member 2 I. v A flexible end ring or washer 28, formed of fiber, sheet aluminum or the. like, is fitted within the internal annular groove 24 in eachsi'de of the housing members l9, said rings or washers being of less diameter than the grooves, as best shown in Fig. 2, so as to hold the two sections of the housing in their proper positions and float with the shaft when flexing of the frame occurs. These rings or washers have the central apertures 29 fitting upon the respective portions of the shaft.
Gaskets 30, preferably shaped. as shown in Fig. 3, with central, semi-circular cutout 3| to conform to the external, annular grooves 22 in the housing members, and with notches 32 near each end to conform to the internal annular grooves 24 in the housing members, are located between the opposed ends of the housing members and the entire assembly is drawn together by means of a U-bolt 33, located within the external annular grooves 22 in the housing members and through suitable apertures in the frame plate 34.
The flat face 23 of the lower housing member l9 rests upon the frame plate 34, and nuts 35 upon the screw threaded ends of the U-bolt draw the assembly together, slightly compressing the flexible cushion strips 21 between the housing members and the outer track ring I l of the roller bearing, as best shown in Fig. 2. Lock nuts 36 may be placed upon the threaded ends of the U- bolt, in contact with the clamping nuts 35, for
ring,'said housing members havin circumferentially extending channels therein,- flat, flexible strips located in said channels, a shaft mounted through the inner bearing ring, and means clamping said housing members together upon the outer bearing ring, said housing members having annular grooves therein on opposite sides of said channel, and end rings fitting around the shaft and extending into said grooves forming a chamber enclosing the bearing rings.
2. A mounting including inner andouter bearing rings with interposed anti-friction bearing members, a pair of substantially semi-circular housing members embracing said outer bearing ring, said housing members having circumferentially extending channels therein, fiat, flexible strips located in said channels, a shaft mounted through the inner bearing ring, and means clamping said housing members together upon the outer bearing ring, said housing members having annular grooves therein on opposite sides of said channel, and end rings fitting around the shaft and extending into said grooves forming a chamber enclosin the bearing rings, said grooves being of greater diameter than said end rings.
3. A mounting including inner and outer bearing rings with interposed anti-friction bearing members, a pair of substantially semi-circular housing members embracing said outer bearing ring, said housing'members having circumferentially extendin channels therein, flat, flexible strips located in said channels, a shaft mounted through the inner bearing ring, ,and means clamping said housing members together upon the outer bearing ring, said housing members having annular grooves therein on opposite sides of said channel, and end rings fitting around the shaft and extending'into said grooves forming a chamber enclosing the bearing rings, and means for admitting lubricant to said chamber.
4. A mounting including inner and outer bearing rings with interposed anti-friction bearing members, a pair of substantially semi-circular housing members embracing said outer bearing ring, said housing members having circumferentially extending channels therein, flat, flexible strips located in said channels, a shaft mounted through the inner bearing ring, and means clamping said housing members together upon the outer bearing ring, said housing members having annular grooves therein on opposite sides of said channel, and end rings fitting around the shaft and extending into said grooves forming a chamber enclosing the bearing rings, said grooves being of greater diameter than said end rings, and means for admittin lubricant to said chamber.
5. A mounting including inner and outer hearing rings with interposed anti-friction bearing members, a pair of substantially semi-circular housing members embracing said outer bearing ring, said housin members having circumferentially extendin channels therein, flat, flexible strips located in said channels, a shaft mounted through the inner bearing ring, a frame plate in contact with one of said housing members, a U- bolt embracing the otherhousing member and means clamping said U-bolt and said frame plate together, said housing members havin annular grooves therein on opposite sides of said channel, end rings fitting around the shaft and extending .into said grooves forming a chamber enclosing the bearing rings, and means clamping said housing members together upon the outer bearing ring.
